In Figures 1 to 11, the numeral 1 marks the frame of a locomotive engine, carrying a bearing 2. An axle is shown at 3, and 4 designates the hub of a drive wheel 5 having an outer groove 6 and aninner groove 7 at the'base of the outer groove. An an,- nular hub plate 8 is slidably mounted inthe groove 6 and has a flange 9 that overlaps 7 the end of the hub 4. A dowel pin 10 engaged with the hub plate 8 and with the hub 4 holds the hub plate against rotation. 'A ram ring 11 is received in an annular re Q cess 12 in the hub plate 8 and extends into the inner groove 7. An abutment ring 14 is seated in the groove 7 and has a cylindrical body 15 slidable in an annular chamber 16 in the ram ring 11, the chamber isforming a central projection 17 having a depress'ion 18 in its end.

The body 15 of the abutment ring 14 has a roughened inner surface 19 that holds a packing 20 on the body portion 15, about the projection 17. v A nipple 21 is threaded into the hub 4 and-has a head 22 that engages the abutmentring 14. l i I A passage 23 leads to the nipple 21 from an enlarged bore 24 in the hub 4. A valve I casing 25 is threaded into the bore 24 and has a Wrench head 26 that bears against the hub 4. There is a cage 27 on the inner end of the casing 25, and a ball check valve 48 \j Works in the'cage and cooperates with a 95 tubular seat threaded into the Valve casing 25 against a lip 29 at the inner end of the casing. r

, A closure plug 30 is threaded into the easm ing 25' and has a socket 31 to receive a tool 109 whereby the plug can be removed. A

nipple 32 is located opposite to the nipple under pressure, forces the ram ring 11- against the hub plate 8, and the hub plate against the bearing 2. The check valve 38 holds the greasexunder pressure and keeps the ram ring 11 seated against the hub plate, and thehub' plate against the bearing.

In Figures 12 to 20, parts hereinbefore described have been designated bynumerals peviously used, with the suffix a. The ram ring 11 and the abutment ring 14 are omitted, and their place is taken by a plurality of cylinders 36 located in the inner groove 7 and connected by pipes 37.

Pistons 38 slide within packings 39 held in the cylinders by the roughened surfaces 40 of the cylinders. All of the cylinders 36 are retained by nipples 21a. Three of the nipples communicate by the passages 23a with the check valve mechanism 48a25a, and the fourth nipplecommunicates bythe passage 33a with the outlet chamber 34a that is closed by the plug a.

r In this form of the invention, the pistons 38 are advanced under pressure to hold the hub ring 8a against the bearing 3a. The

hub plate 8a may be made in sections, halved together as at 41.

In Figures 21, 22, and 23 there is shown a device] of the class described, modified to some extent from the structures which have been described hereinbefore. The axle is shown at 60, and the hub 'of the wheel appears at 61. The hub 61- has an annular groove 62 in which the hub: plate '63 is slidably mounted. I The hub plate 63 has a flange 64 that overlaps'the end of the hub 61. The

hub "plate 63 is transversely divided as shown at 65, to form sections, and the sec tions of the hub plate are tongued and grooved together, as at 66; At its inner corners, the hub" plate 63 is cut awayto form concaved seats 67. r

The hub plate 63 is provided with a V-shaped groove 68, receiving a correspond ingly shaped spreader ring 69, and packings 7 0' are" located in the seats 67 The base of the spreader ring 69' rests against a sheet of asbestos, orany other suitable packing composition, shown at 71, and the sheet 1, in itsturn, abuts against a follower plate 72 which is" divided and tongued and grooved together, as shown at 73. i There is an annular recess 74 in the hub 61 behind the follower plate 72, and from the recess 74, a passage 75 leads, at an incline, to an enlargedbore 76, corresponding to the bore 24 of Figure 3, the numeral 77 designating a valve casing and corresponding parts, such as is disclosed in Figure 3. I

When grease is forced through. the passage 75 into the recess 74, the hub plate 63 will be advanced as hereinbefore described, the grease finding its way entirelyaround the hub, through thefa'nnular recess 74. The function of the spreader ring 69 is to insure pressure fit of the hub plate 63 being practically the same throughout the circumference. This is especially desirable in sectional applications where wheel hubs are bored with lathe, with wheelsaxled, where there is likely to be a slight variance from a true circle. v V

In practical operation it has been found that the fit of the hubplate 63 in the groove spread the hub plate suficiently both toward the inside fitting surface and the outside fitting surface to overcome such imperfections in pressure ,fit as there may be. I In Figure 26, parts hereinbefore described in connection with Figure 21 have been designated by numerals previously. used with the suffix bi In this form of the inven tion, the passage 75?) is not inclined like the passage 75, but is disposed approximately at right angles to the recess 74?). 4

In Figure 24, parts hereinbefore described have been designated by numerals previously used with the suflix 0. A seat 670 hasa groove 78 in its base, and the packingi70c is triangular in cross section with a V-shaped rib.7 9 that extends into the groove 78.

In Figure 25 of the drawings, parts hereinbefore described have been designated by matterof fact, it is suggested that a-recoil oil be employed as a hydraulic fluid, the oil being of the sort used in connection with therecoil structure of pieces of artillery, an oil which will withstand very hightemperatures, such as 365 degrees F.

"The chief object of the adjustable hub plate .is that. it may be adjusted toward the bearing on'the locomotive frame to take up excess lateral play between the driving box and the bearing face of thehub of the locomotive driving wheel, a

' locomotive to maintain the lateral play within the limit allowed by the Interstate Commerce Commissiom'the hub plates being adjusted as the wear on the hub plates and the driving box bearing faces takes place.

I claim 1. A wheel having a slidable hub plate, means for coupling a fluid pressure device to the wheel to put pressure on the hub plate, and means for temporarily relieving the pressure behind the hub plate at the beginning of the operation of the fluid pressure device, thereby to attain an even distribution of the pressure fluid behind the hub plate.

2. A wheel having a groove, the wheel having an inlet leading to the groove and an outlet leading from the groove, a hub plate slidable in the groove, a closure for the inlet, and a closure for. the outlet, the closure for the inlet being removable for the attachment of the pressure device, and the closure for the outlet being removable to permit the exit of air and to facilitate a distribution of the pressure fluid upon the hub plate.

3. A wheel having a groove, an inlet leading to the groove, and an outlet leadin from the groove; an outwardly closing chec valve in the inlet, a removable closure for the inlet, and a removable closure for the outlet.

4. A wheel having a groove, a hub plate slidable in the groove, spaced cylinders in thegroove, pistons slidable in the cylinders and cooperating with the hub plate to advance it, means for establishing communication between the cylinders, an outlet for (cinecylinder, and an inlet for another cylin- 5. A wheel having a groove, a hub plate slidable in the groove, spaced cylinders in the groove, pistons slidable in the cylinders and cooperating with the hub plate to advance it, means for establishing communication between the cylinders, an outlet for one cylinder, an inlet for another cylinder, a removable closure 'forthe inlet, a removable closure for the outlet, and an outwardly closing check valve in the inlet.

6. A wheel havinga groove, a hub plate slidable in the groove, the hub plate having a V-shaped groove in its inner end surface, a correspondingly shaped spreader ring in the groove, a follower plate engaging the spreader ring, and means for deliverlng pressure against the follower plate.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signatnre.
